Description

Technical Field

[0001] The present invention relates to the technical field of access control, and in particular to intelligent security access control based on the Internet of Things. Background Art

[0002] IoT-enabled smart security access control integrates the Internet of Things (IoT) with biometric technology to achieve efficient and intelligent management. This system utilizes advanced authentication methods such as facial and fingerprint recognition to ensure secure access. Its powerful real-time networking capabilities support remote control and data synchronization, facilitating centralized management and monitoring. IoT-enabled smart access control not only improves the convenience of access control management but also enhances security, making it a crucial component of modern intelligent security management.

[0003] Despite their critical functionality, the barrier structures used for interception in current smart security access control systems often suffer damage due to various factors. Since these barriers are typically secured to the access control shaft with fasteners such as bolts, replacement requires the tedious removal of these fasteners before the barrier structure can be replaced. This process is complex and time-consuming, especially in high-traffic locations. Long maintenance efforts can disrupt the smooth operation of security operations and affect overall safety efficiency. Summary of the Invention

[0004] The embodiment of the present disclosure relates to an intelligent security access control based on the Internet of Things. It changes the pass baffle into a sliding setting. When the two pass baffles are in a relatively closed state, the pass baffle can be restricted on the opening and closing shaft under the action of the corresponding structure, so that the pass baffle cannot slide, thereby ensuring the stability of the pass baffle in the use state. At the same time, when the pass baffle is in a horizontally open state, the corresponding structure will cancel the restriction on the pass baffle, so that the pass baffle can be separated from the opening and closing shaft by simply lifting it upward. In this way, the switching state of the pass baffle is used to match the fixed and movable states of the pass baffle, which fully improves the convenience of disassembly, assembly and replacement of the pass baffle, does not spend too much time on replacing the pass baffle, and is not likely to interfere with the smooth progress of security work due to replacement of the pass baffle. It is suitable for security places with dense traffic.

When the pass slider is not rotated, the no-entry sign appears in the indicator window; when rotated, the pass sign appears. This mechanical indicator requires no additional power, is energy-efficient, and durable, making it more economical and practical than electronic screen indicators. BRIEF DESCRIPTION OF THE DRAWINGS
